How Long Will Krylon Last In The Can?

I know y'all are going to shoot me for this, but I've got paint issues on my truck, and don't have the means or cash to get the whole thing repainted correctly. Last year I had reasonable success sanding the flaking paint and rust off the roof and recovering with auto primer and flat black paint. Yes, aerosol Krylon. I could have done a better job if I had better sandpaper, but not a single place for miles around had anything better that would fit the rented random-orbit sander (which wasn't really up to the task either). I knew it wasn't going to last but I did the best I could with what I had. It actually lasted much longer than I expected.

Anyways.....

Rust never sleeps, and it's time to do it over again. The hood is starting to flake up too, so I wanted to hit it before it actually began rusting. I've got better equipment to work with this time, but no time to do it. This part of the world is unseasonably cold at the moment (highs less than 70F) and every fecking weekend it has been raining. I've been procrastinating, I know. Should have done this six weeks ago when it was 85 out, I know. I don't have a garage. It might warm up again this year, but there are no guarantees.

If I don't get to do this until spring, should I return all the paint I've purchased (and not used), or will it be ok in the can for several months? I'm pretty sure it'll last, just not 100% sure.

Thanks

No oxygen in that can. The paint's good for probably ten years, Maybe more.

Store it inside (don't let it freeze) and it will be just fine.

I've had cans of krylon, rustoleum, and others, primer, enamel, plastic in my garage for several years. They still work good. They survive 120F just fine. The only time I lost any was when it got below freezing for several days a few years ago. The outsides of the cans will rust though.

If it was me doing the work I would return all the Krylon and go buy real auto spray paint in a can. It's not that much different in price but usually a little higher. I used to use Krylon type paints to paint my shiny black parts like the spare tire carrier and bumpers and it didn't last a year before the sun pretty much took all the shine out of it. Since I switched to real auto spray paint (the stuff Pep boys and AUtozone type places sell) it lasts for several years. I've used it to do real repaints of small areas in colors too and it's held up well.

I looked at the auto stores and they had pretty much the same stuff. Some of it just some 'off brand' spray paint.

FWIW I'm painting with flat black and wetsanding to a minor sheen. I'm not too concerned with shininess.

If I had the facility and/or cash I'd take the whole thing down to bare metal and blast it with some DP-90 primer sealer, but you know... ;)

That was not the OPs issue with his paint cans. I've gotten several well done small paint repairs with those auto spray can paints and a couple of not as great looking large area repairs done with them. The main problem isn't that they are over thinned or watery, it's that they dry too fast to do a large area properly. Small areas often come out very well with them. A second problem of course is that there is no way to color match to faded paint.

You make the common mistake of assuming that if you can't do something no one else can.

Who can get a decent paint repair with auto paint in a spray can, a skill that eludes you with your 40 years of experience. But don't take my word for it, you said so yourself. As I said, you make the common mistake of assuming that because you can't do something no one else can.

Then as usual, you'd be wrong.

Yeah, you do that if it makes you warm and fuzzy.

Krylon will last indefinitely in the can. After some time you'll have trouble getting it out.

Excellent!

Actually, I was able to complete my Shade Tree Engineering paint repair job. I spent a lot of extra time on it and paid lots of attention to details, etc. Hopefully I'll get a full year out of it, this time.

In the meantime, I think I'm going to call around some body shops and see what they'd ask to take my hood off, sandblast it, DP-90 it, and put it back on. Don't even bother with any straightening, wetsanding, etc. Runs, orangepeel and fisheyes are ok, as long as the primer stays on there.

It can't hurt, doubt it will break the bank, and they can do a helluva better job than me. Maybe I can reclaim that kbb resale value of $1200. w00t!
